Polished Mobile Gacha Style splash art for a rare character card, dynamic three-quarter view, cowboy shot. RKN-chan, a glamorous woman in her late twenties with long pale blue hair with blunt bangs tied in two high pigtails flowing in a magical wind and sparkling blue eyes, swings her glowing ban hammer in a wide arc with a playful wink. Her pigtails are held by dark blue cube-shaped hair clips marked with a single straight white line running across the cube from edge to edge, interrupted in the middle by a hollow white square. She wears a long double-breasted blue jacket with two rows of round gray buttons, light blue piping, black epaulettes and pointed coattails, white scalloped cuffs, a white shirt and a narrow dark blue tie, light blue leggings and blue knee-high boots. On her left sleeve is a white-bordered polygonal patch bearing the bracket emblem: a tilted square made of two thick angular bracket shapes. The upper-left bracket is light blue and opens toward the lower right, the lower-right bracket is dark blue and opens toward the upper left, and they face each other around a small dark blue square in the center, separated by narrow white gaps. The ornate silver card frame has the bracket emblem at its top corner: a tilted square made of two thick angular bracket shapes. The upper-left bracket is light blue and opens toward the lower right, the lower-right bracket is dark blue and opens toward the upper left, and they face each other around a small dark blue square in the center, separated by narrow white gaps. A name banner at the bottom of the card reads RKN-chan, with five gold stars above it. Shards of broken screens and blue light particles burst around her. Glossy rendering, bright highlights, blue, white and gold palette.
